Approval process

Once your tokenization request is submitted by following the steps in Toucan's Puro Bridge Partner Integration Guide (request access here), it needs to be approved by a Toucan Verifier, a trusted member of the Toucan community. This step is required to protect against fraudulent inputs and is dependent on human action and trust, for now. However, we will automate this process in the future.
Once the correctness of the serial number input is confirmed by a Toucan Verifier, the BatchNFT is minted and fractionalized into an equivalent number of fully fungible ERC20 tokens which we call TCO2 tokens. The "T" here stands for "Toucan" - or "tonne" — or "tokenized" — and 1 TCO2 token represents 1 carbon credit with a value of 1 tCO2e. So, an NFT representing a batch of 100 credits can be fractionalized into 100 TCO2 tokens.
